CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 497,930, dated May 23,1893.

Application led June 29, 1892.

To all whom it may concern:

Be it known that I, LOUIS NAPOLEON SIN- GIN, a citizen of the UnitedStates, residing at Wall, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inCar-Couplings, of which the following is a specification.

My invention relates to car couplers, and more particularly to automaticcouplers of what is known as the vertical plane style, and it has forits object to provide a coupler which shall be exceedingly simple inconstruction, positive and automatic in its operation, cheap tomanufacture, and effective in use.

To these ends my invention consists in a coupler embodying the featuresof construction substantially such as are hereinafter more particularlyset forth.

Referring to the accompanying drawings, Figure 1, is a plan view of thedraw-head with one section of my coupler applied thereto. Fig. 2, is asimilar view partly in section of the complementary draw-head. Fig. 3,is a side View; and Fig. 4, is a longitudinal vertical section of thedraw-head.

In carrying out my invention it is one of the objects to provide adrawhead and coupler which is not only simple and effective in use, butwhich can be readily removed from a car in case of accident and a newdrawhead or portion of the coupler readily replaced, not requiring theuse of any special tools or the turning of the cars into the shops forrepairs;

The drawhead l is madein the usual shape generally adapted for use inconnect-ion with this class of couplers, and may be attached to the carin the usual way, it not being deemed necessary to show it herein. Theconfiguration of the drawhead is such as to comply with the usualrequirements of this class of couplers, so that it will beinterchangeable with couplers of other makes, and is provided with theprojections 2, 3, the body of the drawhead being hollow as shown in Fig.2, for the reception of the operative parts of the coupler. Mounted inthe projection 2 `of the drawhead is the knuckle 4, and this is providedwith the usual slot 5, for the reception of the ordinary coupling link,and with apin hole 6, for the reception of the ordinary coupling pinSerial No. 438,424. (No model.)

'when the coupling is to be used with the old style link. The knuckle 4has an extension 7, projecting at substantially right angles to theknuckle, and this extension is in the form of a sector, and is providedWith a number of teeth 8, 9, l0, ctc., four being shown in the drawings,although 1 do not limit myself to the precise number.

Mounted in the drawhead is the sector 12, having aseries of teeth 13,14, 15, duc., the tooth 17 at one side of the sector being` preferablymade larger or thicker to form a strong bearing portion for the sector.This sector is pivotally mounted in the drawhead in such a position thatits teeth normally engage with the teeth ofthe projection 7 of theknuckle so that the two sectors move in unison, one with the other.

In order to lock the knuckle in position, I provide a locking pin 20.This pin While it may be variously made, is preferably of a shape shownin the drawings, having an extension 2l, which forms a guide passingthrough the opening 22 in the under portion of the drawhead, while theupper portion is formed at an angle having the parts 23A and 24, andfitting an angular opening 25 in the upper portion of the drawhead. Thepart 24 is shorter than the other portion, so that when the pin israised as shown in Fig. 4, the teeth of the sector l2, pass underneaththe pin, and the pin slides or moves over the face of the sector, butwhen the sector is in the position shown in dotted lines Fig. l, the pinfalls by gravity and the portion 24 thereof impinges or bears againstthe enlarged tooth 17 of the sector and forms a safe and secure brace tohold the knuckle of the coupler in couplingA position.

The locking pin may be operated in any usual manner, from the top or theside of the car by suitable mechanism, which need not be shown, and itis preferably locked in the coupler head, so as not to be liable to bedisplaced. The knuckle is secured in the drawhead by a pin 26, and asector 12, is secured in position by a similar pin 27, and it will thusbe seen that if any accident happens to the knuckle or the sector,either or both may be readily removed from the drawhead and a new onereplaced, it only being necessary to raise the pins 26 and 27,`andsubstitute the proper part for the injured part.

Such being the construction of the device, its operation will be readilyunderstood. When the parts are to be coupled, one of the coupling pins2O is raised, and the knuckle thrown out, so that the parts assume theposition shown in Fig. 2, and when the complementary knuckle of theother drawhead is brought into position, the knuckle 4: thereof willstrike against the projecting sector 7 of the open knuckle, and forcethe parts into place, the teeth of the sector 7, turning the sector 12to the position shown in dotted lines Fig. l. Meanwhile the locking pin20 rides over the upper surface of the teeth of the sector, and when theknuckle is forced home to the proper position, the pin falls by gravity,so that its wide portion 24 engages the rear of the tooth 17, and theparts are securely locked in position. It will be seen that in thisposition not only the strongest portion of the locking pin, but of thesector, are in contact and more or less of the teeth of the sector andof the projection interlock, and form a strong and secure bearing. Whenit is desired to uncouple, it is simply necessary to raise the lockingpin 20, and separate the draw bars. It is not necessary to raise the pinof both drawheads.

While I have thus described and illustrated the preferred embodiment ofmy invention, it will be understood that the details of construction andarrangement may be varied without departing from the spirit of myinvention, and I do not therefore limit myself to the preciseconstruction shown.

What I claim isl. In a car coupler the combination with the drawhead, ofa pivoted knuckle havinga sector provided with projecting teeth, and apivoted sector having teeth continually en-.

gaging the teeth ofthe knuckle, substantially as described.

2. In a car coupler the combination with the recessed drawhead, of asector having teeth pivotally mounted therein, a knuckle having a sectorprovided with projecting teeth continually engaging the teeth of thesector, and means for locking the sector, substantially as described.

3. In a car coupler the combination with the drawhead,of the knucklehaving a sector shaped projection provided with teeth, a scctorpivotally mounted in the drawhead provided with teeth continuallyengaging the teeth of the knuckle, and a locking pin engaging saidsector, substantially as described.

4. In a car coupler the combination with the drawhead, of the knucklehaving a sector shaped projection provided with teeth, asector pivotallymounted in the drawhead provided with teeth continuously engaging theteeth of the knuckle, anda locking pin having an angular body arrangedto engage the sector, substantially as described.

5. In a car coupler the combination with the knuckle having a sectorshaped projection provided with teeth, a pivoted sector mounted in thedrawhead also provided with teeth continuously engaging the teeth of theknuckle, one of the teeth of the sector being enlarged to form a bearingportion, and a locking pin engaging said enlarged tooth, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LOUIS NAPOLEON SINGIN.
